unique-cidr-manager

A basic tool build to manage unique CIDR across networks

This tool is built in order to manage the private range ip addresses in the organization network to avoid future potential routing conflicts.

How it Works

• An env file should be provided in order the set all the required parameters using '--env-file .env' while running docker Required parameter name and values:

name	description	value
access_token	your personal token for the repo that will contain the unique list of occupied CIDRs	ghp_3KR4U7bxxxxxxxxxxxxx
occupied_repo	the name of the owner+repo in github.com	xmcyber/infra

• The tool will first clone a dedicated repo (your own repo) that will maintain the final and unique list of occupide ip ranges.
• After getting the required major range, it will start choosing first subnet (cidr) in this range, for example 10.0.0.0/26
• Than it will read the already occupied ranges from 'occupied-range.json' file (which should be created in your repo, {} content should be enough) and check if that occupied, if its overlaping it will go to next available range.
• After getting the UNIQUE cidr, it will return the the CIDR to web browser.
• Last step, it will append the new CIDR to the occupied-range.json and will push the change to your repo

Docker

unique-cidr-manager is very easy to install and deploy in a Docker container.

docker build -t image:tag .

docker run -d -p 8000:8000 --env-file env -name unique-cidr-manager unique-cidr-manager:latest

Verify the deployment by navigating to your server address in your preferred browser.

http://localhost:8000

Here are some examples for request

Obtain new CIDR:

http://localhost:8000/get-cidr?subnet_size=${subnet_size}&requiredrange=${required_range}&reason=${reason}

Show all occupied CIDR list:

http://localhost:8000/get-occupied-list

Delete CIDR from list:

http://localhost:8000/delete-cidr-from-list?cidr_deletion=10.1.2.3/28
